Unformatted text preview: 10. What is the overall composition of the eutectic microconstituent? 11. Each of the following phase diagrams ad has and error. Circle the error. 12. Explain the error in 11a. 13. Explain the error in 11b. 14. Explain the error in 11c. 15. The following contains the pressuretemperature unary phase diagram for Bismuth. From this diagram, explain how you can determine that melting Bismuth at 1 atm results in a reduction in volume, and consequently, freezing Bismuth at 1 atm results in an expansion in volume. That is to say, at one atm, the volume of solid bismuth is greater than the volume of the liquid. 16. Using the ternary isotherm below , determine the relative amounts of , , and for a composition of 1/3 A, 1/3 B, and 1/3 C. 17. Using the same isotherm, determine the composition of a structure that contains 1/3 , 1/3 , and 1/3 ....
